Manufacturing facilities are complex ecosystems of waste streams and hazardous materials, especially across aerospace, rail and automotive manufacturing. Appropriate disposal, storage and transport of hazardous materials is essential to ensuring personnel safety across sites.
Emma Cooke, Operations Manager, at waste and tech specialists at Envirovue, explains how a thorough, process-driven approach is essential to reduce risk and prioritise safety across manufacturing processes.
The emphasis on safety in manufacturing is increasing, and pressure on businesses to implement people-first processes is mounting. Plants are highly regulated environments and hazardous substances are utilised in different ways, making specialist waste-management essential to ensure safety.
An array of safety challenges
Manufacturing parts for the aerospace, rail and automotive industries is far from linear. All sectors rely on a wide variety of hazardous materials and substances to support engineering and manufacturing across cooling systems, treatments and cleaning operations.
These range from battery chemicals, coating materials, fuels and a variety of gasses. Complex storage and transportation are necessary due to the number and variety of these chemicals and materials such as acetic acid, used for paint and adhesives, often need to be transported between multiple sites and require specific storage.
Every step of the manufacturing process exposes risks to workers, contractors and transportation operators. Inadequate segregation and incorrect storing are some common causes of hazardous occurrences.
Emphasis should be placed on frontline operational safety, but the risks and dangers relating to poor waste management practices, infrastructure where chemicals are stored and transportation between sites should not be underestimated.
To ensure safe disposal, storage and transport of hazardous materials, it is important to keep an inventory of all hazardous substances on site. Understanding and classifying the various hazards by corrosiveness, flammability, toxicity and environmental risk can significantly reduce risk for personnel interacting with the material.
Manufacturing teams should also implement procedures such as clear labeling, ensuring materials are stored in the appropriate containers and segregation. Ensuring isolated and specific storage areas are available is also recommended – particularly effective in minimising risk in the event of a spill.
It is also necessary to implement frequent checks and reviews of materials at various steps of the manufacturing and transportation process. In order to ensure stability of hazardous materials and monitor that it is being handled in accordance with the appropriate regulation, paperwork is key to keeping all employees safe across individual touchpoints.
Digital tracking systems and waste management software are also becoming increasingly important tools for manufacturers handling hazardous materials. Greater visibility across materials allows businesses to move beyond reactive management and identify inefficiencies, bottlenecks and potential safety risks before they escalate.
Tracking systems provide real-time oversight of storage conditions, movement between sites, container status and disposal pathways, helping create stronger audit trails while reducing reliance on manual processes.
Ultimately, better data enables manufacturers to make more informed operational decisions, improve compliance reporting and create safer, more efficient processes across complex manufacturing environments.
Safety implications of chemical storage failures
Mishandling waste can not only impose immediate danger to people, but it can compromise legislation and risk fines and breaching the law, resulting in regulatory penalties, significant reputational harm for organisations and also the contamination of water supplies and soil, creating a public health concern that extends far beyond the facility itself.
One of the most significant concerns from sites producing parts for aerospace, rail and automotive is the incorrect handling and storage of reactive materials such as ferric chloride, hydrogen peroxide and acetic acid. These chemicals can cause fires, explosions and serious burns if mixed with other chemicals or stored incorrectly.
Ferric chloride is a highly corrosive chemical compound widely used across industrial applications, most notably in water treatment processes where it plays a key role in removing impurities. The compound is also used in the production of specialist chemicals and manufacturing processes, including applications involving lightweight component production and sensor technologies.
Despite its widespread industrial use, the chemical presents significant handling and storage challenges due to its corrosive nature. Exposure to incompatible materials or inadequate containment systems can accelerate equipment degradation, leading to infrastructure damage, leaks and potentially hazardous releases. In the event of spills or containment failures, ferric chloride can generate corrosive vapours that present additional operational and safety risks.
As a result, infrastructure consideration is critical when managing ferric chloride throughout industrial processes. Storage tanks, transfer systems, pumps and pipework must be constructed using corrosion-resistant materials capable of withstanding prolonged chemical exposure to minimise the risk of system failure.
One of the growing challenges facing manufacturers is that while production processes, materials and technologies continue to evolve rapidly, safety procedures and chemical management practices do not always keep pace.
As sectors such as aerospace, rail and automotive accelerate innovation through advanced materials, lightweight components, battery technologies and increasingly sophisticated manufacturing techniques, the hazardous substances being introduced into facilities are also changing.
In many cases, however, storage infrastructure, handling procedures and waste processes may have been implemented years earlier when facilities were originally established or designed around very different operational requirements.
Processes that were once considered appropriate can quickly become outdated if they are not regularly reviewed, creating potential blind spots around chemical compatibility, containment infrastructure and operational risk. Regular reassessment of hazardous material management is therefore becoming increasingly important to ensure safety systems evolve alongside manufacturing environments rather than lag behind them.
The risks also extend beyond infrastructure and equipment and into workforce safety. Direct contact with ferric chloride can result in severe skin burns and eye damage, while exposure to vapours may cause irritation to the eyes, nose, throat and respiratory system, particularly in poorly ventilated environments.
Appropriate PPE, ventilation controls and handling procedures are essential safeguards for personnel working with the compound. Meanwhile, from a storage perspective, ferric chloride should be kept within tightly sealed, corrosion-resistant containers, stored in cool, dry and well-ventilated environments away from direct sunlight.
Separation from incompatible substances, including metals, alkalis, strong oxidising agents and reducing agents, is also essential to reduce the risk of unwanted chemical reactions.
Hydrogen peroxide is a chemical that also presents unique challenges across industrial manufacturing due to its reactive nature and widespread use in surface preparation, cleaning and material processing.
As a powerful oxidising agent, contamination or exposure to elevated temperatures can trigger rapid decomposition, generating gases that create pressure build-up and increase the risk of explosion. Where combustible materials are also present, incidents can escalate quickly, making temperature control, ventilation and segregation essential considerations throughout storage and handling processes.
Implementing best practices
For manufacturers operating within high-risk environments, however, materials management extends far beyond storage alone. Aerospace, rail, automotive and wider industrial sectors increasingly face pressure to improve visibility across hazardous material streams while maintaining compliance, efficiency and operational resilience.
A comprehensive review of material flows and waste streams is often the starting point. Many manufacturers continue to operate using legacy handling models or reactive processes simply because they lack the time, resources or operational visibility needed to fully assess how hazardous materials move throughout sites. Without this understanding, opportunities to reduce waste, improve reuse and eliminate inefficiencies are often missed.
Tracking and traceability therefore play an increasingly important role within hazardous manufacturing environments. Robust segregation at the point of generation helps prevent cross-contamination and ensures materials can be handled according to their specific storage, treatment and regulatory requirements. Maintaining clear documentation and audit trails throughout storage, movement and disposal processes is extremely important and this paperwork will provide manufacturers with greater accountability while supporting regulatory compliance.
Technology, monitoring systems and workforce education also have an important role to play. Employees must understand not only how to identify and segregate hazardous materials correctly, but also why these processes matter.
Better visibility across material streams allows manufacturers to identify opportunities for reuse, improve circularity initiatives and move away from reactive operational models towards more proactive risk management strategies.
Ultimately, as manufacturing environments become increasingly complex, organisations that combine robust segregation processes with stronger tracking capabilities and greater operational visibility will be better positioned to improve safety outcomes while maintaining efficiency and compliance.
